However, not only has JIT behavior evolved in that amount of time, the main external claim appears to have been that the `int position \u003d this.position;` local variable optimization was lost at that time, with one the first comments on that issue noting that restoring that also fixed the regression.\n\nToday, all available benchmarks suggest that this should be good change to make (with the local variable position optimization included), ~twice as fast for direct Uint32 writes usages.\n\nPiperOrigin-RevId: 913780730\n"

(#26598)\n\nIn issue #11146 people reported problems with the PHP package version 3.20.0RC3 and above crashing when the native extension was used with protobufs that had transitive dependencies. [This comment](https://github.com/protocolbuffers/protobuf/issues/11146#issuecomment-1939557722) noted that it looked like an issue with the dependency list being modified.\n\nThis PR resolves the issue by also removing public and weak dependency references in the emitted PHP metadata classes.\nI\u0027ve added a unit test showing that it compiles OK, but the unit tests don\u0027t exercise the PHP side so I\u0027ve taken the liberty of extending the reproducer case kindly provided by @tforesti and pushed a version that shows the fix to [github.com/alowde/php-protobuf-ext-issue](https://github.com/alowde/php-protobuf-ext-issue/tree/master). The [Dockerfile](https://github.com/alowde/php-protobuf-ext-issue/blob/master/DockerfileOKPatchedLatest) builds a copy of `protoc` from my branch and shows that the patched version doesn\u0027t cause a crash on import when the image is launced.\n\nAn LLM was used to investigate the issue and write the unit test, with human review. The fix itself and the fix demonstration  were written by @alowde. The fix demo builds on the failure case Dockerfile by @tforesti to provide a clear demonstration of the fix.\n\nPlease let me know if any further information or changes would be useful.

This produced invalid JSON that could not be parsed by other systems.\n\n### Solution\n- Updated php/src/Google/Protobuf/Internal/GPBJsonWire.php to use `sprintf(\"%.*h\", ...)` for formatting values. This ensures that the decimal separator is always a dot (`.`), making the output locale-independent.\n- Added a new test case testJsonEncodeFloatLocaleIndependent in php/tests/EncodeDecodeTest.php. This test explicitly sets the locale to `de_DE` to verify that the fix works correctly and produces valid JSON.\n\n### Verification\n- [x] Added new regression test.\n- [x] Verified that all PHP tests pass locally: `vendor/bin/phpunit php/tests/EncodeDecodeTest.php`\n\nFixes #18808\n\nCloses #25329\n\nCOPYBARA_INTEGRATE_REVIEW\u003dhttps://github.com/protocolbuffers/protobuf/pull/25329 from khdkkhdd:18808-php-float-fix 5de303962e25d43c3c5e99b8ae7295008f7527aa\nPiperOrigin-RevId: 911348844\n"

      "message": "Fix is_map_ type check in CrossLinkField for TYPE_GROUP fields (#27218)\n\n## Summary\n\n`CrossLinkField()` sets `field-\u003eis_map_` based solely on whether the referenced message has `map_entry: true`, without checking the field\u0027s own type. This causes `TYPE_GROUP` fields pointing to a `map_entry` message to incorrectly have `is_map_ \u003d true`, violating the invariant already documented by the DCHECK in `is_map()`:\n\n```cpp\n// descriptor.h:3081\ninline bool FieldDescriptor::is_map() const {\n  ABSL_DCHECK_EQ(is_map_, type() \u003d\u003d TYPE_MESSAGE \u0026\u0026 is_map_message_type());\n  return is_map_;\n}\n```\n\nIn release builds (`-DNDEBUG`), this DCHECK is compiled out, so the incorrect `is_map_` value silently propagates to all downstream consumers.\n\n### Downstream impact\n\nOver 20 call sites rely on `is_map()` to make correctness-critical decisions:\n\n- **Wire format** (`wire_format.cc`): `is_map()` gates deterministic serialization via `MapKeySorter`, byte size computation via `map_field-\u003esize()`, and unknown enum handling via `map_value()-\u003eenum_type()`. An incorrect `true` causes these paths to call `GetMapData()` on a non-map repeated field.\n- **Reflection** (`message.cc:721`): `is_map()` selects `MapFieldAccessor` vs `RepeatedPtrFieldMessageAccessor`. Wrong accessor type for the underlying storage.\n- **Parsing** (`generated_message_tctable_gen.cc:615`): `is_map()` assigns `fl::kMap` type card, routing the field through map parsing instead of message parsing.\n- **Merge/diff** (`reflection_ops.cc`, `message_differencer.cc`): `is_map()` gates `MergeFrom()` on `MapFieldBase*` and `CompareMapField()`. These dereference map-specific internal state that doesn\u0027t exist on a group field.\n- **Codegen** (`cpp/field.cc`, `cpp/message.cc`, `java/helpers.h`): `is_map()` controls generated accessor methods, constructor initialization, and cross-file dependency tracking.\n- **Text format** (`text_format.cc:2822`): `is_map()` gates `SortMap()` for deterministic printing.\n- **UTF-8 validation** (`descriptor.cc:10763`): `is_map()` triggers `map_key()`/`map_value()` access for string validation checks.\n\n### Root cause\n\nThe `is_map_` assignment at the original location (before type inference at lines 8076-8090) runs before `field-\u003etype_` is finalized. Additionally, `TYPE_GROUP` fields legitimately reference messages with `map_entry: true` but should never be treated as map fields -- maps always use `TYPE_MESSAGE` wire type.\n\n### Fix\n\nMove the `is_map_` assignment into the `CPPTYPE_MESSAGE` block (after type resolution and `type_descriptor_.message_type` null check), and add a `type_ \u003d\u003d TYPE_MESSAGE` guard. This makes the runtime assignment match the invariant the DCHECK already enforces.\n\n## Test plan\n\n- Added `GroupFieldPointingToMapEntryIsNotMap` regression test: creates a `TYPE_GROUP` field referencing a `map_entry` message, verifies `is_map()` returns `false`.\n- All existing `*Map*` descriptor tests pass (no regression).\n\nCloses #27218\n\nCOPYBARA_INTEGRATE_REVIEW\u003dhttps://github.com/protocolbuffers/protobuf/pull/27218 from jortles:fix-is-map-type-check 5e7da139772096dc5d47e1bb75197dbf2c5b8a23\nPiperOrigin-RevId: 911096352\n"

      "message": "Check for uint16_t field_count overflow in upb_MtDecoder_Parse() (#27133)\n\nIn the field parsing logic of `upb_MtDecoder_Parse()`, the `uint16_t field_count` is incremented for each parsed field with no overflow check. A MiniTable with more than `UINT16_MAX` fields will then wrap the field counter. This sets the `upb_MessageDef.layout-\u003efield_count` to an invalid value smaller than the total number of fields. `upb_MtDecoder_ParseMessage()` then calls `upb_Arena_ShrinkLast()` with the wrapped `field_count` size.\n\nLater `_upb_MessageDef_LinkMiniTable()` uses `int m-\u003efield_count` as an index loop bound  for `m-\u003elayout-\u003eUPB_PRIVATE(fields)`, creating a mismatch between the array and index bounds.\n\nTo fix the bug, I opt for a simple integer overflow check before incrementing.\n\nThis bug has been reported to [Google\u0027s OSS VRP](https://issuetracker.google.com/u/0/issues/503166184).\n\nCloses #27133\n\nCOPYBARA_INTEGRATE_REVIEW\u003dhttps://github.com/protocolbuffers/protobuf/pull/27133 from mowteam:fix-upb-field-count-overflow 0baffe0a994e22e243d5c7530f9c3975d64efed7\nPiperOrigin-RevId: 910682441\n"

      "message": "Fix an endian problem when memcpying in _upb_Decoder_DecodeEnumPacked (#25683)\n\nThis is related to the endian fix in https://github.com/protocolbuffers/protobuf/pull/25363. My colleague @saisindhuri91 found another place that needed to be fixed. It fixes a the upb test `MessageTest.Proto2Enum` on big endian platforms.\n\nThe fix is in the `_upb_Decoder_DecodeEnumPacked` function. An older version of the function had a call to munge the elem value but it had been removed when the unknown enum value handling was improved. It is still needed when, later in the the function, there is a `memcpy` that is expecting a 4 byte value. I have placed the call to `_upb_Decoder_MungeInt32(\u0026elem)` after the new call to `_upb_Decoder_AddEnumValueToUnknown(d, msg, field, \u0026elem)` so it will only affect the `memcpy`.\n\nCloses #25683\n\nCOPYBARA_INTEGRATE_REVIEW\u003dhttps://github.com/protocolbuffers/protobuf/pull/25683 from linux-on-ibm-z:upb-decode-endian-2 e54b8e148d36888ce6daa922659fb4dd30550060\nPiperOrigin-RevId: 910042959\n"
